sorry, but the only idea i know how to communicate is UDP, that is why im looking for better solution or ideas,
How much experience to you have of UDP programming?
Have you got a working Arduino program that can receive UDP messages?
can i extend the cable of the machine? what cable i will use? because on my idea i just use lan cable and rj45
I don't know if you are referring to my comment in Reply #15 about extending the power cables? I was referring to the cable that brings electric power to the washer. I was not referring to any data cables.
dekdimaya:
here's my scenario. customer goes to staff in the payment system/computer server pay what ever she need. and the staff just receive cash then click paid for what ever service she/he likes, then the system automatically send messages to the machines, so it records the payments and the machine will only get credits on what ever the system sends. they cannot operate the machine unless it receive signal
I had suspected you were thinking of a payment system like that. But what I don't understand is why the washing machine needs to know anything about the payments. Surely all it needs is to be allowed to work, or be prevented from working.

I could imagine that the OP is trying to utilise as much of the existing logic of the washing machine control system as possible and simply intends to simulate coins being inserted in the machine. So, for example, if three coin pulses gives X amount of use of the machine, he simply wants to send remotely a signal which simulates 3 coin pulses across the wires which are exposed after he has removed the coin mechanism.

yes!

i done this before using udp, as control for computer client in a computer shop payment and control system

will not touch anything about the power source of the machine, will work only for the interface shown above. and the machine have corresponding built in system for the payment.

yes! and this is I want to do with arduino, so please help me can I do it with 1 arduino+ethernet? then 10 machine? or 1 arduino+ethernet per machine?
and also help me how to send signal or pulses, this is i have no idea on how to do it.. thanks again guys

OK - I have a much better picture of what you want to do now.
But you have not said whether you have a working example of sending a UDP message to an Arduino. Get that working as the first step.
Secondly, do you know how the various coin-box connections work (those shown in your photos)? Or are you looking for advice about that also? If so I have never had anything to do with one of them.
Thirdly, if you DO know how all the connections work, can you describe the outputs that you need from the Arduino. I can probably help with that part.

i have but it is a pc to pc, just like telnet sample, i saw some example i hope it does work.

not at all, even the LOW & HIGH.. i have some idea but not really sure for it... and this is the one I really need help...
Thirdly, if you DO know how all the connections work, can you describe the outputs that you need from the Arduino. I can probably help with that part.
i need arduino to receive data using Ethernet from computer using: UDP or as simple as net send command
sample data:
"COIN1"
"COIN2"
then once arduino received this message... arduino will process this and send signal to COIN/INTERFACE then the machine automatically get credits, its in the machine system already. all i need is to know how to do it.
thanks man
Why did you start a new thread here ?
Your project is obviously a continuation of this: Controlling Washer/Dryer Using LAN - Project Guidance - Arduino Forum where the same questions and issues are again dealt with.
I think you may want to shift this across to the Gigs and Collaboration section.
You really need someone with adequate hardware experience to work through this with you. Ideally in the same state/city so they can test ideas and share the knowledge with you.I'm in Melbourne Australia, others may be closer!
Id still be pushing for the serial interface.
yes and they advice me to move to different section gigs and collaboration, but i think i still need project guidance on what to use and what to do initially as i still have no idea where to start.
I have created new topic because my old topic is the selection of what to use, and i have decided to use the coin interface now. do i have to change section?
thanks
Since you've already done it, my suggestion is to leave the thread here. If you find you are getting too far out of your depth, and want to hand the development over to someone on a fee basis, then get a moderator to merge your threads and move them all ove to Gigs and Colaborations.
As has been pointed out to you, you have at least two main problem areas to solve:
- The communication between your central node and the Arduinos in each laundry machine.
- The interface between each Arduino and the laundry machine it controls.
To get confidence that you have the basis of a solution, my suggestion is to, at an early stage, devote som time to analysing the interface that the coin drop provided because this is what you are trying to emulate. I guess the circuit that is depicted in post #21 is contained in the coin drop which you are replacing. Incidentally the quality of the picture is very poor and it is not possible to read component values etc. It also appears that the numbers on the connector (1-9) in the schematic do not correspond closely with the photograph of the connector and the numbering of the wires (1-8) and (1-2).
Anyway, it looks like you are really only interested in 2 of the connectors, the coin1 signal and the coin2 signal. With an arduino, a simple sketch, 2 relay modules and some passive components, you could simulate inserting coins into the system. A relay is recommended because it isolates your circuit from that of the laundry machine. What function, incidentally, do the 2 additional contacts have, that is those marked "Coin Box" and "Coin SVC" ? Are these also used to validate the entry of a coin into the system ?
Have you a photograph of the coin mechanism, especially of its contacts and its circuit board ?
The circuit diagram in #31 which I presume is the circuit diagram of the signal part of the coin acceptor mechanism (which you say you have not got) shows a connector labeled 917729-1 Natural.
Such a connector looks like this.
The picture of the connector you have shown coming out of, I presume, the laundry machine clearly (apart from the colour - Natural) does not match. The type and number of pins is different.
If you problems getting hold of all the documentation and you don't have sufficient knowledge to trace wires back etc., then it does look like you need someone at your location to help out with developing an interface between to the laundry machines.
If you still want to do the networking part yourself, you could specify the task as something like this:
- Analyse the available documentation.
- Develop hardware and software to simulate a coin acceptor mechanism which accepts 2 types of coin and service switch operation.
- Prerequisites: Arduino based solution with USB interface for software update etc. Must be expandable to include Ethernet adapter (if that is what you want).
- Deliverables: Hardware, Source program
- Acceptance test(s):
Connect hardware to laundry machine X. Connect serial console. Issue "coin1" on serial console. Laundry machine must respond to coin1. Do the same for all the other features specified.
Payment conditions: to be negotiated.
If you get that bit working, you can then attempt to develop your networked solution.
If you want to proceed like that, get the thread moved into Gigs and Collaborations and see what happens. Move the thread by using the "report to moderator" link in the post and explain what you want.
I don't think I can contribute anything more to this activity, but wish you good luck with it.
@6v6gt thanks a lot for your time i really appreciate it, will follow your advice ill just to do some complete documentation first. then will update this thread and move to gigs... thanks to all.
admin thank you for moving...
guys anyone willing to help me to this project? willing to pay fees, just let me know.. thanks
hi, would like to know, if I can use Arduino Mega, then attached multiple cable for each machine. Is this possible to do?So I will only need Mega then cables. Then my system will just send using port then arduino process the data? please help thanks
It seems to me like the problem is a lot more difficult in your mind than it is in reality. I was following your first thread, and to an experienced dev, it's a day of discovery, another day of developing the strategy, then whatever time you need to buy and build the modules.
Allow another two days to test and rework. Done.
Pay someone, and assuming you can articulate your requirements... the problem will be solved and working in less time than you've spent on these threads.
Some are outwardly simple, but cost more, while others that you may not understand may be more reliable and cheaper to implement.
Go to Gigs & Collaborations.
or do I need to connect all that pin in the coin interface?
Nothing says you can't learn and be part of it, but it sounds like you're not ready to 'make informed decisions' yet, and the thread will die a slow death before you get there.
Not trying to be discouraging, but you have several levels of understanding to grasp, and haven't really hooked on to #1 from what I can see. Starting a new thread just discards contributors that want to help.
Perhaps if you say where you are geographically in general, someone may (PM) offer to meet up in the near future, and sketch out / discuss the alternatives. You'll learn a lot, and can interactively question the options put forward.
Doing it entirely online is in reality a huge risk - because me and/or others may be completely clueless and lead you up the wrong path.
Okay thanks will try 
Anyone here in Manila Philippines?
Please message me. Thanks
maybe posting your number isn't such a good idea, but anyone in Manila can PM you, and get you running
Edit & delete the phone number as soon as you can!
Just change that line to "Please contact me if you can help in Manila"
Good luck!
